General

Delivery and Handling

The weight and size of the Powertank may require the aid of lifting equipment and must be handled in a safe manner.

Inspection

On delivery, the Powertank should be inspected thoroughly and any damage reported to the supplier as soon as possible. This should be confirmed in writing within 48 hours.

Applications

The Powertank is designed for domestic and light commercial pressure boosting.

The Powertank should not be installed in areas that are classified as hazardous or where there is a risk of an explosion or harm to people. The manufacturer does not accept responsibility if the Powertank is used to pump liquids other than clean water unless suitability has previously been agreed in writing.

Warranty

All mechanical components of the Powertank are covered by a 12 month warranty against manufacturing defects. In case of failure please contact the Technical Department on 01543 415200.

Site Storage

Should a Powertank need to be stored before installation it should be in a safe place away from moisture, dust and frost.

Installation Checklist1. Check the unit for any visual defects. Contact your supplier immediately if any are found.

2. Choose a suitable location for installation. Please ensure the unit is fitted and supported in accordance with these instructions.

• Check that the cold water storage tank capacity is designed to meet your water consumption demands.

• Tank Drip Trays or bunded tanks are to be used for Installations that would be sensitive to leakage.

3. Connect the inlet pipe work and overflow pipe work as per the installation diagram.

• Good quality full bore Isolation Valves should be fitted before and after the unit to allow for reliable service or repair.

• We strongly advise that a suitably designed bypass is installed to allow for servicing.

• Pipe work should be easy to disassemble. Consider the use of “Speedfit” or similar plastic pipework systems, or flexible hosing with a suitable pressure rating, for the last 1.0 mtr (approx.) of pipe work connecting to the unit. This will reduce noise transmission and accommodate movement of the unit, avoiding stressing the Powertank connections.

• Pipework installations should be in accordance with local water authority regulations.

• The Powertank COMPACT is designed to accept a 40mm overflow pipe. Other tanks should be fitted with overflows in accordance with local regulations. Ensure that overflow water is piped away properly.

4. Fill the storage tank with water through the fill valve before connecting the discharge pipe work to allow air to escape from the pump. Please ensure the fill valve fitted is suitable for the incoming water pressure.

5. Once the tank is full, connect the discharge pipe work as per the installation diagram.

• The discharge pipe work must be, at a minimum, the same size as the Powertank inlet supply; if it is smaller the result will be reduced pressure and flow at the outlets.

• The discharge pipe work must be properly secured so once the Powertank is fitted there are no stressed internal pipe work.

6. In accordance with the latest IEE regulation all electrical connections should be carried out by a qualified electrician .The Powertank must be earthed. It is recommended that an earth leakage circuit breaker (ELCB) is fitted on the incoming electrical supply.

• Make sure the electrical supply is fully isolated and cannot be turned on before working on the pump, motor, controller or any part of the unit.

• Do not turn on electrical supply to the Powertank without ensuring all electrical fittings and all covers are intact and fully isolated from human touch during operation.

POWERTANK

Location Consideration

The Powertank is not recommended to be fitted above ceilings.

Installations in loft areas are not recommended due to the weight of the tank when full of water and the increased potential for damage in the event of water leakage or spillage. Sound also travels through rafters and it is likely that such an installation will be noisy compared to an installation on a solid base.

Installations significantly higher than the mains water stop tap will reduce the refill rate of the tank.

1. The Powertank should be installed in a dry, well-ventilated area where it is not exposed to extreme temperature or frost. An ambient temperate below 20 °C is required to limit bacteria growth. Powertanks may be located outdoors in a weather, frost and rodent proof enclosure which should be adequately ventilated during warm weather.

2. All pipe work that may be exposed to freezing condition should be fully protected.

3. Powertank must be positioned such that there is safe access for examination and service in compliance with health and safety practice.

4. Bunded tank options and drip trays are available for some of the Powertank range and these can be used in areas where water spillages or leakages can cause damage.

5. A litre of water weighs 1kg so a 200 litre tank will weigh 200kgs plus the weight of the tank, pumps etc. See our technical data sheet for the dry weights of each Powertank. Please check that your proposed installation site can support this level of load evenly.

6. There should ideally be adequate lighting in the location of the Powertank for ease of maintenance.

7. There should be sufficient space allowed above the tank to allow for correct installation of the pipe work and the removal of the pump from the tank for inspection and maintenance. We recommend the space allowed should be at least two-thirds the height of the tank.

Foundation & Mounting

Powertank must be mounted on a solid foundation to support the weight of the unit. Surfaces must be flat and level to spread weight load evenly. The recommended surface for a Powertank is a concrete plinth or floor. We do not recommend installation of Powertank units on wooden structures in any situation where noise or vibration may be an issue.

Storage Tank

Powertanks incorporate a cold water storage tank with a type AF Air gap as standard (AB Air gap for the Compact model) and when used with a mains connection must be installed in accordance with the water regulations. All the wetted parts of the Powertank are potable quality and suitable for use with drinking water. It should be noted that the quality of stored water deteriorates over time if ambient temperature is greater than 20 degrees Celsius (>20 °C). If the tank is to be left idle for any length of time, it is recommended that it is completely drained before being put back into use. It is recommended that tanks are drained and cleaned periodically, according to the conditions of use, to avoid any problems.

Slave Tank

Where additional water storage is required, a slave tank can be used to increase the capacity. It is important to maintain the “flow through” of all the water and to achieve this the incoming water supply should be delivered to the slave tank only. Please contact us for guidance on a particular installation.

Pipework Installation

It is recommended to install a cold water mains bypass to allow an emergency water supply to the property to be maintained during service or failure. This allows the home owner to have a low pressure supply available while the unit is out of commission. The bypass must be installed in accordance with the water By-law regulations and should be drained to prevent water stagnation when not being used.

Electrical Installation

Powertanks supplied with a fitted plug may be used with a domestic 13A power socket. The plugs have a 13A fuse and, in the event of failure, should be replaced with the same value. Pumps supplied with only a power cable are designed for professional installation and should be connected by a suitably qualified electrician in accordance with the latest IEE regulations.

Ensure that the electrical supply is fully isolated before removing any electrical covers. The Powertank is fitted with a 3 core cable and the earth wire must be connected. It is recommended that an earth leakage circuit breaker (ELCB) is fitted on the incoming electrical supply.

Single phase Powertanks are suitable for voltage supply 230v +/- 10% with a suitable MCB or Fuse rated at a maximum of 13A. See below for the full load current of our different Powertank Pump options.

Commissioning

1. Make a visual check to make sure all pipe work and electrical connections are connected securely in a safe manner.

2. If present, close any isolation valves on the Bypass and disconnect the bypass if necessary to comply with water regulations.

3. Check that the Pre-charge air pressure in the pressure vessel is set 0.2 bar below the cut in pressure. For a standard fixed speed Powertank with a 1.5 bar Presflo this would be 1.3 bar. For variable speed units with user selectable start pressures it should be set according to your required duty point.

4. Check and open the isolation valves on the inlet to the tank.

5. If the tank isn’t already filled, loosen the outlet connection to allow air to escape while the tank is filling.

6. Ensure the tank is full and there is no discharge from the overflow connection.

7. Check that the outlet connection has been correctly tightened again and close the valve you have fitted on the outlet pipe.

8. Open the closest cold water outlet to the tank.

9. Check that the unit is plugged in or the electrical supply cables are correctly connected to the mains isolator switch.

10. Turn on the power. The control unit should turn on and the pump start to run for up to 30 seconds.

11. Slowly open the Isolating valve to fill the pipe work with water, the pump should start automatically. If it does not then you may need to press the “reset” button or turn the power on again.

12. If the controller displays dry running after approximately 10 seconds it is likely that there is air trapped in the pump. Bleed this air out by loosening the lower connection of the control unit before resetting the controller. This is O ring sealed and does not need to be overtightened or have any joint sealer.

13. Check that water is flowing from the open tap/outlet and then close it and check that the pump turns off. There will always be a time delay of 10 – 20 seconds until the pump stops in normal operation.

14. Check all pipe work for leaks.

15. For variable speed Powertanks, check the operating pressure and adjust as required.

Vessel Pre-charge Pressure

The air pre-charge in the pressure vessel should be set 0.2 bar below the pump start pressure for maximum effectiveness. It is recommended to check the Tank air pressure every 4-6 months. For fixed speed Powertanks the air pressure in the vessel should be 1.3 bar.

Fixed Speed Powertanks - Pressure Settings

The start pressure is 1.5 bar on a standard fixed speed Powertank and is not user adjustable. These Powertanks are not suitable for installations where the highest outlet is more than 12 vertical metres above the Powertank, please consult our Technical Department for heights greater than this.

Water Quality

In the event that the water remains unused inside the tank for an extended period, it should be drained and flushed to maintain water quality. Tanks may be drained by using the pump to empty it and/or via the drain plug at the base. For commercial applications the tank should be cleaned in accordance with the relevant regulations and it is recommended that domestic systems are drained and cleaned twice a year or as required by the circumstances of the installation.
